I vote for Image Dynamics...I've used 2 12 IDQs v2s awhile ago. I loved those subs got pretty loud and sounded good doing it. My friend ran 2 10" IDmaxs in his silverado also nothing but great sound they get louder than his 4 10" clarion that he as in there right now. My mom also runs a 10" idq in her Vette. It sure sounds nice
